This is a typical pop culture/celebrity gossip market. While the Met Gala is a major fashion event, predicting the attendance of a specific celebrity (Lady Gaga) is a niche entertainment topic rather than a broad societal issue.

April 28, 2026 - April 28, 2026, Option_'Yes' price plunged from 88.5c to 49c, rebounded to 88.5c, and settled at 71.5c. This extreme intraday volatility was driven by panic selling and aggressive profit-taking due to the lack of official confirmation just days before the event, exacerbated by opportunistic dip-buying. April 25, 2026 - April 28, 2026, Option_'Yes' price surged from 73c to 88.5c, as more authoritative fashion media or insider leaks confirmed her schedule closer to the gala, removing final market doubts. April 24, 2026 - April 27, 2026, Option_'Yes' price surged from 64.5c to 83.5c, likely because as the Met Gala approaches, the market captured strong insider confirmations or explicit hints from mainstream media, leading to a massive influx of bullish capital. April 13, 2026 - April 14, 2026, Option_'Yes' price fell from 84.5c to 71c, as the market faced a lack of further official confirmation following the rapid run-up, leading to profit-taking by bullish investors and a short-term pullback. April 11, 2026 - April 13, 2026, Option_'Yes' price surged from 62c to 84.5c, likely because, as the Met Gala approached, the market picked up strong insider rumors or designer leaks regarding her custom outfit, massively boosting bullish expectations. April 5, 2026 - April 8, 2026, Option_'Yes' price surged from 37c to 56.5c, likely because the market detected a favorable gap in her tour schedule or new insider leaks emerged, fueling a strong bullish rebound. March 31, 2026 - April 1, 2026, Option_'Yes' plummeted from 51.5c to 18c, as the market realized she is occupied with her 'Mayhem Ball' tour and hasn't attended the Gala since 2019, leading to a collapse in bullish confidence and heavy sell-offs due to the lack of official confirmation. March 23, 2026 - March 24, 2026, Option_'Yes' plunged from 88.5c to 65.5c, as the market faced concentrated profit-taking after pushing prices significantly higher, lacking immediate catalysts to sustain the peak. March 20, 2026 - March 21, 2026, Option_'Yes' tumbled from 83.5c to 53c, indicating extremely fragile confidence among holders in the absence of official confirmation, triggering panic selling. March 13, 2026 - March 14, 2026, Option_'Yes' price retraced from 64c to 58c, as speculative capital took profits after a brief rally that was not sustained by official confirmation. March 5, 2026 - March 8, 2026, Option_'Yes' price drifted down from 54c to 46.5c, driven by profit-taking after the previous rally and a drying up of buy-side volume due to a lack of new confirmation. March 1, 2026 - March 2, 2026, Option_'Yes' rebounded sharply from 42.5c to 55c, likely a technical correction to the previous day's drop or driven by thin market depth where small buy orders cause outsized moves. February 28, 2026 - March 1, 2026, price plunged from 55c to 42.5c, highlighting the fragility of holder confidence and the extreme volatility caused by illiquidity.

Significant rule risk exists. First, the text identifies Mojtaba Khamenei as the current Supreme Leader, which conflicts with current reality (Ali Khamenei), unless this is a future-conditional market. Second, defining 'de facto leader' is subjective, especially during power struggles or illness; pinning down the exact moment of 'ceasing to lead' could be contentious.

This is a geopolitical prediction. While leadership change is a standard topic, specifically naming Mojtaba (usually seen as a successor, not incumbent) as the target for removal makes this market somewhat speculative and specific.

A leadership change in Iran carries extremely high geopolitical uncertainty. A sudden power shift or coup would directly threaten oil transit through the Strait of Hormuz, causing severe volatility in Crude Oil prices. Gold would also react significantly as a safe-haven asset. This is a classic high-impact geopolitical risk event.

A key trap in the rules is that an 'announcement of resignation/removal immediately resolves to Yes, regardless of when it goes into effect.' Also, acting/interim officials are excluded, and the list of covered positions is extremely broad (ranging from the President and Congress members to State Governors and Fed officials), requiring only one to unexpectedly leave before the end of their scheduled term prior to April 30, 2026.

The novelty of this market lies in bundling hundreds of high-ranking US officials into a single probability pool, betting on whether ANY of them will abruptly leave office within an extremely short timeframe (by April 30). While official turnover is common, this packaged short-term 'death cross' style market is somewhat unusual.

April 28, 2026 - April 29, 2026, the price of Option_'Yes' plummeted from 54c to 4.5c-6.5c, likely due to market doubts about whether the resignation events qualify under the specific rules of this market, or abnormal volatility caused by illiquidity. April 27, 2026 - April 28, 2026, the price of Option_'Yes' spiked from 12c to 54c, driven by bets on the rule trigger following news of several U.S. Representatives announcing their resignations. April 24, 2026 - April 26, 2026, the price of Option_'Yes' briefly spiked from 38c to 50c, before falling back down to around 17.5c-21c. This was due to delayed market reactions or fluctuating interpretations of the rules regarding the news of several U.S. Representatives announcing their resignations, leading to significant price volatility.

Significant divergence exists. According to public information and market rules (which state resolution to Yes immediately upon announcement of a qualifying official's resignation), the event has already occurred. However, the current prediction market price (5.5c) reflects an extremely low probability, suggesting the market is either ignoring this information or holds extreme concerns that the platform might refuse to resolve as Yes for some reason.

Predicting the exact number of posts by a public figure in a specific week is a classic novelty market. Unless they are betting, general audiences rarely care about such granular data.

April 27, 2026 - April 28, 2026: The Yes price for the 60-79 option surged from 0.75c to 32.7c, and the 80-99 option surged from 14c to 55.5c. This was due to a downward adjustment in posting pace expectations for the specific time window, combined with structural distortions in the order book. April 26, 2026 - April 27, 2026: The Yes price for the 120-139 option rose from 16.5c to 32c, as early forecasting funds identified this bracket as closely aligning with his historical average output.
